Class GetNextBlockGenerators

The GetNextBlockGenerators API will return the next block generators ordered by the
hit time. The list of active forgers is initialized using the block generators
with at least 2 blocks generated within the previous 10,000 blocks. Accounts without
a public key will not be included. The list is
updated as new blocks are processed. This means the results will not be 100%
correct since previously active generators may no longer be running and new generators
won't be known until they generate a block. This API will be replaced when transparent
forging is activated.

Request parameters:

limit - The number of forgers to return and defaults to 1.

Return fields:

activeCount - The number of active generators

height - The last block height

lastBlock - The last block identifier

timestamp - The last block timestamp

generators - The next block generators

account - The account identifier

accountRS - The account RS identifier

deadline - The difference between the generation time and the last block timestamp
